“A powerful storm system will bring localized wind gusts of 50 mph or more Saturday,” the Weather Service’s hazardous outlook said. “Mountain ridge tops and other locations exposed to west winds will have the best change of experiencing strong winds.”

In Okanogan County, those winds are expected to affect the Methow, Chewilikin and Tunk valleys, as well as Wauconda and the Okanogan Highlands. The winds are also expected to buffet Sherman Pass, Keller and the Curlew areas of Ferry County.

Weather officials said residents may see some “power outages and localized damage to trees.”

In addition to the high winds, elevations above 4,000 feet may see another foot or more of snowfall between Friday and Sunday.

At lower elevations, meteorologists are predicting a rain-snow mix Friday, turning to rain by Saturday morning.

In the Grand Coulee and Waterville areas, the storm is expected to produce winds of 30-40 mph Saturday, weather officials said. Gusts could reach as high as 55 mph
